Abstract
A pigment composition comprising a) a pigment; and b) a phthalocyanine compound having the formula I: MPc(CH.sub.2 NHCO--A).sub.n I in which Pc represents a phthalocyanine residue which is optionally further substituted by up to an average of one chlorine or bromine atom or by a sulphonic acid group; M is hydrogen or a metal capable of forming a metal phthalocyanine; n is a number ranging from 0.1 to 4.0; and A is C.sub.3 -C.sub.21 alkenyl, C.sub.5 -C.sub.8 cycloalkyl, C.sub.7 -C.sub.11 aralkyl, C.sub.6 -C.sub.10 aryl, a 5- or 6-membered heterocyclic residue or a fused heterocyclic system.
